One of the best ways to search for properties is by zip code. Without a Thomas Guide just figuring out what zips to use can be a difficult task. No more. Goolgle’s new software, Google Earth, takes care of that. It’s like Portland Maps gone worldwide. You have to download the software and have a broadband connection but it is cool.
You can turn off different layers. On these two maps, I have streets and zips turned on (click on the image to enlarge).
